WCM, as the sole general partner of Partners and Partners I, has the sole power to direct the voting and disposition of the shares of Common Stock that Partners and Partners I beneficially own.

Beneficial ownership of the Common Stock shown on the cover pages of and set forth elsewhere in this Schedule 13D for each member of the Wynnefield Reporting Persons assumes that they have not formed a group for purposes of Section 13(d)(3) under the Exchange Act, and Rule 13d-5(b)(1) promulgated thereunder. If the members of the Wynnefield Reporting Persons were deemed to have formed a group for purposes of Section 13(d)(3) and Rule 13d-5(b)(1), the group would be deemed to own beneficially (and may be deemed to have shared voting and dispositive power over) in the aggregate 860,750 shares of Common Stock, constituting approximately 5.3% of the outstanding shares of Common Stock (the percentage of shares being based upon 16,344,193 shares of Common Stock outstanding as of April 26, 2013, as set forth in the Issuer’s most recent report on Form 10-Q for the quarter ended March 31, 2013, filed with the Commission on May 10, 2013).

The filing of this Schedule 13D and any future amendment by the Wynnefield Reporting Persons, and the inclusion of information herein and therein with respect to WCM, WCI and Messrs.
